This is a starter template for building AI agents using PydanticAI and CopilotKit. It provides a modern Next.js application with an integrated investment analyst agent that can research stocks, analyze market data, and provide investment insights.

Prerequisites

OpenAI API Key (for the PydanticAI agent)
Python 3.12+
uv
Node.js 20+
Any of the following package managers:
- npm (default)
- pnpm
- yarn
- bun

Getting Started

Install dependencies using your preferred package manager:

# Using npm (default)
npm install

# Using pnpm
pnpm install

# Using yarn
yarn install

# Using bun
bun install

Note: This will automatically setup the Python environment as well.

If you have manual issues, you can run:
npm run install:agent

Set up your OpenAI API key:

Create a .env file in the project root with the following content:

OPENAI_API_KEY=sk-...your-openai-key-here...

Start the development server:

# Using npm (default)
npm run dev

# Using pnpm
pnpm dev

# Using yarn
yarn dev

# Using bun
bun run dev

This will start both the UI and agent servers concurrently.

Available Scripts

The following scripts can also be run using your preferred package manager:

dev - Starts both UI and agent servers in development mode
dev:debug - Starts development servers with debug logging enabled
dev:ui - Starts only the Next.js UI server
dev:agent - Starts only the PydanticAI agent server
build - Builds the Next.js application for production
start - Starts the production server
install:agent - Installs Python dependencies for the agent
